+    <h2>Ratioed Plugin Help</h2>
+    <p>
+      This plugin provides administrators with additional statistics about
+      the behaviour of users.  These may be useful as early warning signs
+      that warrant more carefully watching the behaviour of a user.  They
+      are <em>not</em> suitable as a trigger for instantly blocking,
+      muting, or reporting a user, since they lack context.
+    </p>
+    <p>
+      The name of the plugin comes
+      from <a href="https://knowyourmeme.com/editorials/guides/what-is-the-ratio-and-what-does-it-mean-to-get-ratioed-twitters-1-rule-explained">"The
+        Ratio"</a>, a well-known quick rule of thumb:
+    </p>
+    <blockquote>
+      If the Replies:RT ratio is greater than 2:1, you done messed up.
+    </blockquote>
+    <p>
+      To "get ratioed" is to receive a large number of comments in a short
+      space of time, with relatively few likes or boosts.  If commenters
+      were enthusiastic about the posts, they would also have liked or
+      boosted them.  Receiving many comments without such likes or boosts
+      indicates the comments were probably angry.  This anger may or may
+      not be justified, but either way this is probably something
+      moderators should be aware of.
+    </p>
+    <p>
+      This plugin allows viewing of an actual ratio, calculated over the
+      last 24 hours.  This is a useful timeframe for sudden dogpiling
+      events that administrators might not otherwise notice.  The plugin
+      also calculates other statistics.
+    </p>
+    <h3>Explanation of Statistics</h3>
+    <h4>Blocked by</h4>
+    <p>
+      This summarises the number of users on remote servers that have
+      blocked this user.
+    </p>
+    <p>
+      Note that the ActivityPub spec expressly says that
+      implementations "SHOULD NOT" forward such block messages to
+      remote servers.  Nevertheless some implementations do this
+      anyway, notably Mastodon.  This statistic can only count block
+      messages from servers that do this, as well as blocks from local
+      users.  As such, it is usually an undercount.
+    </p>
+    <p>
+      The reason the spec recommends against forwarding these messages
+      is that they can lead to retaliation.  For this reason, this
+      plugin deliberately does not provide any way to investigate
+      exactly who blocked the user.
+    </p>
+    <h4>Comments last 24h</h4>
+    <p>
+      This gives the number of comments made on the top-level posts that
+      this user made within the last 24 hours.
+    </p>
+    <h4>Reactions last 24h</h4>
+    <p>
+      This collects the number of likes, boosts, or other "one-click"
+      interactions made on the user's top-level posts within the last 24
+      hours.
+    </p>
+    <h4>Ratio last 24h</h4>
+    <p>
+      This is the ratio between "Comments last 24h" and "Reactions last
+      24h".  It is intended to approximate the traditional ratio as
+      understood on Twitter.
+    </p>
+    <h3>Performance</h3>
+    <p>
+      The statistics are computed from scratch each time the page loads.
+      It's possible that this might put a heavy load on the database. and
+      the page may take a long time to load.
+    </p>
+    <h3>Extending</h3>
+    <p>
+      Suggestions for additional statistics are welcome, especially from
+      moderators.  This plugin should be considered a sandbox for
+      experimentation, so it is not necessary to prove that any statistic
+      is correlated with unwanted behaviour.
+    </p>
+    <p>
+      However, this plugin does deal with potentially sensitive
+      information.  Even if moderators do in principle have access to all
+      information, it should not necessarily be highlighted.  Statistics
+      should be kept anonymous and neutral.  Also, they should be
+      presented only to moderators, not to the users themselves.
+    </p>
